System Events.app startup problem

Recently I noticed my Macbooks fans where spinning all the time for no apparent reason.

Upon further investigation I found out every single time I reboot my Macbook an application titled "System Events" will use up 50-60% of my CPU (continuously) until I force quit it from within the Activity Monitor and after this it will happily idle at around 3% presumably doing what ever task it does.

I didn’t want to outright delete the application as I have no idea what it does and its also inside a folder labeled "Core Services", seemed like an area to tread carefully within.

At least I have found a relatively simple work around but I was wondering if there is anyway to stop this happening all together?

So far I've tried to disable each application that is being loaded on startup one at time to see if its any of them, Ive also tried adding and deleting the offending System Events application from the startup applications.

Ive had no luck so far so any help will be much appreciated, if you need any further information on my Macbook I will be more than happy to provide it.

Thanks for reading.

EDIT: Ive also tried leaving the Macbook running while I was at work for around 6 hours, when I came home System Events was still at 60%, the logic behind doing this was to see if it was doing some sort of task system wide and I wasn’t giving it enough time to execute.
